Specification of Letters Patent.

Patented July 3, 1917'.

Application filed February 16, 1917. Serial No. 148,950.

To all whom it may concern:

Be it known that we, JOH F. Srnvnns and Jncon G. DAVIS, citizens of the1 United j and it has for its primary at Ottumwa, in the county Statesresidin l 7 State of Iowa, have inventof Wapello an edcertainnew anduseful Improvements in Cattle-Stanchions, of which the following is aspecification.

This invention relates to certain new and useful improvements inlcattlestanchions aim to provide a novel and simple construction in which thecattlemay be conveniently locked and released. I f f 1 1 Further, theinvention resides in yield ably mounted stanchion embodyingi'animprovedlockingYmeans for thewyoke parts be adjusted to vary the sizefor the particular animal. 1 r

The. invention further resides in the improvements, features ofconstruction, and arrangements and combinations of parts hereinafterdescribed and succinctly claimed, reference being hadto the accompanyingdrawing wherein-7- zontally disposed bar 6 Figure 1 is a front elevationof ourimproved stanchion; I.

Fig. 2's an irregular section online2-2 ofFig.l; m Fig. 3 is a verticalsection through Fig. 1 on line 3-3; and

Fig. i is adetailed section of the yoke locking means, said view beingtaken on line H of Fig.2.

Referring more in detail to the accompanying drawing, the numeral 1designates upper and lower stall frame members to which the stanchion isattached, the latter comprising a fixed yokepart 2 which has its lowerend. curved and pivotally connected to the similarly shaped end of themovable yoke part 3 bypin 4:, each yoke part being respectivelyconnected to the lower frame member 1 by, a spring 5, as shown inFig. 1. The upper end portion of the fixed yoke part isfixedin the bendofa U-shaped, horiwhich is guided the upper end of the movable yokepart; the outward ,limit of. swing the springs,

gages the keeper between the legs of engaging the under ofthe latterbeing defined by the stop block '7 that is held in position between thelegs by a bolt 8. This bolt passes through registerlng openings 9 in thelegs, a seriesof such openings being provided so as to afford the blocka plural'ty of adjustments by selectively engaging the bolt in the baropenings, I

and provide a variable sized opening be tween the yoke parts. c I V Acoiled spring 10 connects the yoke bar 6 with the upper framemember .1,said spring being stronger than the springs 5 since the former suspendsthe yoke and constitutes the sole support therefor. It is thus obviousthat the yoke is yieldably and resiliently mounted, the spring 5 thatconnects the movable yoke part 3 to the lower also serving to open theyoke by pulling the movable yoke part outwardly against the block 7 whensaid part is unlocked.

As a safe guard against the cattle lounging forwardly or exerting unduetension on normally slack chains 11 and 12 are provided, the upper chainconnecting the bar 6 to the superposed frame member 1 while the lowerchain 12 is anchored to the lower frame member and attached to the pivotpin 4 so as tobe centrally secured to the lower side ofthe yoke.

xThe movable yoke part is provided with slot 13 through which extends acatch 14:

being constantly urged upwardly by a coiled spring'16 which is connectedto the opposite end of the catch and is anchored to the part 3, as isclearly seen in Fig. at. The latch end is formed with a cam face 17that, when the movable part is closed, en-

18 to permit of the latch part passing said keeper whereby the spring 16will effect a proper interlocking of said parts. The keeper is rotatablydisposed between the legs of the yoke bar 6 on a shaft 19 which carrieson a projecting end a fixed lever 20. This lever is urged in one,direction by a coiled spring 21 the extent of swing being determined bya stop 22, formed by inturning the lower end of said lever, side of saidbar 6. The keeper is provided with kicker part 23 frame member 7connecting the bar to the members connecting the member, one for eachyoke'part, a cham conwhich, when the lever is pulled against the actionof the spring 21, will rotate with said keeper and engage the camface17in pushing the catch from engaging relation with i the keeper.

Mounted on'the inner'e nd of theyo'ke bar is a pulley housing 24 inwhich is ournaled a double pulley 25. A pair of cables or ropes passunder the double pulley and over a guidmpulley 26 to a convenient point,the

only necessary to pull, on rope 27. which draws the movable. part .3toward thefixed ;yoke part 2fand' thelatchfintoengagement with. .thekeeper by the cooperation of :spring. 16'.

-It will be noted, that. the operation is eX- ceedin'gly 'simplefand maybe performed from a ,distantpoint, the construction is xdiirable andembodies but few parts, and the mount1ng 1s such as'to be lnofienswe andnoneinjnrious to the cattle;

1e foregoing detailed description has been :given; for clearness ofunderstanding only, and withno intention offlimitin'g the ffldevice to.the specific disclosure, it. beinguir derstood thatlminor changes asmay fall :within the scope of theclaims may be rerso'rtedito torenderthe structure practical.
